Diving in doesn’t mean diving in blind. To me it does; diving into water is the alternative to going in slowly and cautiously; your talk is more like "look before you dive" - and discussing by mixing metaphors won't clear anything up. You plan, anticipate roadblocks and judge how much you can overcome them in advance, and adjust the plan. To me, that's not diving in, even if you do it quickly; "Diving in" would suggest that you first learn about the roadblock when you get to it and then your progress stops until you overcome it or can't.
